I am trying to use the HUAWEI 4G Usb-Dongle E3372 with Ubuntu 20.04 but the module doesn't seem to work.

ubuntu@yolo:~$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 018: ID 12d1:14dc Huawei Technologies Co., Ltd. E33372 LTE/UMTS/GSM HiLink Modem/Networkcard

Do you have any advice?

Update:

As soon as you plug the usb Dongle in and you get a steady blue led, issue:

ip link
5: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
    link/ether 00:aa:bb:cc:dd:00 brd ff:ff:ff:ff:ff:ff

you should get an eth1 as physical device.

If you are using network manager to handle connections, create an ethernet connection using eth1 and bring it up

sudo nmcli connection add type ethernet con-name huawei ifname eth1
sudo nmcli c up huawei
